JAMES F. BAILEY, OF JACKSONVILLE, FLORIDA, ASSIGNOR OF ONE-HALF TO FRANKLIN '1. SUTHERLAND, OF JACKSONVILLE, FLORIDA.

WRENCH.

To all whom it may concern Be it known that I, JAMEs F. BAILEY, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, .and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in wrenches, and has for its object to provide a wrench which will be easily and quickly adjusted.

Another object of my invention is to provide a wrench which will perform the same functions as an alligator wrench, but will provide one of the above class in which the jaws are adapted to be adjusted.

A further object of my invention is to provide a wrench which may be easily and quickly adjusted by rotating the handle ortion.

A still further object of my invention is to provide a wrench wherein the rotating portion of the handle will be made of sufhcient size to insure proper adjustment of the jaws at all times.

WVith the above and other objects in view, 1

I will now proceed to describe my invention in the following specification and accompanying drawings, in which,

Figure l is a side view of my improved wrench in elevation; Fig. 2 is a longitudinal sectional view of my improved wrench; Fig. 3 is a detail View of a fragment of the a-w holding portions; Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 2; Fig. 5 is a transverse sectional viewtaken on line 55 of Fig. 2; Fig. 6 is a detail view of-t'he jaw operating mechanism, showing the same with the jaws applied; Fig. 7 is a .lngitudinal sectional view of the modification of my improved wrench; and Fig. 8 is .a transverse sectional view taken on line 88 of Fig. 7.

Referring to the drawings by characters of reference, 1 indicates a stationary handle portion, while 2 indicates the rotating handle portion. The jaw receiving portions are indicated at 3 and are provided adjacent their outer extremities with an enlargement 4:. This enlargement is provided intermediate its sides and adjacent its ends with an aper- Specification of Letters Patent.

ture adapted to receive a bolt 5, which is secured therein by means of the nut 6.

The bolt 5 extends through the members formed on the portion 8 and is adapted to act as :a pivot on which the jaws 7 and 8 are adapted to swing. These jaws 7 and 8 are provided .adjacent their outer extremities with the nut engaging surfaces 9. The opposite ends .are extended, as clearly illustrated at 10., and provided with the angular extensions 11, the use of which will be more fully hereinafter described. At the point 5, where the jaws are pivoted, they are cut away as will :be seen upon referring to Fig.

6 of the drawings, and this cut away portion extends from the point 12, at which the jaws meet, and extend rearwardly to the ends of the jaws.

The rota-table portion 2 of the handle is inturned, as clearly illustrated at 18, and is adapted to, form .an annular collar around the sleeve 1 of the handle portion. Adjacent the extremity opposite. the inturned portion, I preferably provide apertures through which screws 14 are adapted to pass. These screws extend inwardly, as clearly illustrated in Fig. 2, and are screw threaded into the rotating member 15, which is provided with the longitudinal screw threaded aperture 16. A shoulder 17 is provided around the outer periphery of the rotat-ing member 15, against which the rotating member 2 of the handle is adapted to abut. A reduced portion .18 is formed integrally with the rotating member 15 and extends into the member 1 of the handle portion. This reduced portion 18 terminates, as is clearly illustrated in Fig. 2, and forms shoulder 19 against which the portion 1 of the handle abuts. Intermediate the shoulder 19 and the inner extremity of the reduced portion, I preferably provide an annular groove 20, through which the pins .22 are adapted to extend, as will be more fully hereinafter described.

In the fixed sleeve 1 I preferably provide the two semi-cylindrical sections 23 and 241, which terminate at their outer extremities in the arms 25 and 26, which form the jaw re ceiving portion previously referred to as 3. These semi-cylindrical portions are provided with longitudinal grooves which form a longitudinal aperture through their center when they are in position. Pins 27 are adapted to extend through apertures in these semicylindrical members, and their ends are adapted to' project into apertures formed in the sleeve 1. These apertures in the sleeve 1 are formed substantially in the middle of said sleeve, so that they will come in direct alinement with the apertures in the semicylindrical portions. I also provide apertures adjacent one end of the sleeve, which are adapted to receive the ends of the pins 22, these pins 22, as previously described, being adapted to cooperate with the annular grooves in the rotating sleeve 15 and hold said sleeve firmly in place.

A plunger 28 is provided adjacent one extremity with a reduced portion 29 which terminates in an enlarged cylindrical portion 30, having screw threads around its periphery, This cylindrical portion 30 is adapt ed to be received in the screw threaded apertures 16 of the revolving member 15, and it will be seen that upon rotation of the member 15 the plunger 28 will be caused to slide longitudinally through the grooves formed in the semi-cylindrical members. The end of the plunger 28, opposite the end 30, is preferably enlarged, as clearly illustrated in Fig. 6, and provided with upstanding portions 31 which extend outwardly from the surface of the plunger and are adapted to engage the angular portions 11 formed on each of the jaws. These portions 31 are provided with cam faces 32, which engage the angular extensions on the jaws and cause the same to open or close as the operator may desire when the device is in use.

The construction of the handle portion of the modification is substantially the same as that above described. The main differ ence between the modification and the above is that the movable jaw is rigidly secured to the plunger, so that upon rotation of the handle direct adjustment of the jaw is secured.

While in the foregoing I have shown and described the preferred embodiment of my invention, I wish it to be understood that I may change the specific arrangements of parts without in any Way departing from the spirit and scope of my invention.

Having thus fully described my invention, what I claim is: I

1. A wrench comprising a cylindrical sleeve, semi-cylindrical halves secured within the sleeve, extensions formed at the ends of said semi-cylindrical halves, a plunger Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

adapted to cooperate with the cam faces on the jaws, whereby adjustment of the jaws is obtained.

2. A wrench comprising a cylindrical sleeve, semi-cylindrical halves secured within the sleeve, extensions formed at the ends of the semi-cylindrical halves, a plunger slidable longitudinally through said cylin drical halves, an enlarged screw threaded portion formed at one end of the plunger,

lateral extensions formed at the opposite end of said plunger, said lateral extensions being provided with cam faces, jaws pivotally secured between the extensions, a revolving portion, said revolving portion being internally screw threaded and cam faces formed on the jaws and adapted to cooperate with the cam faces on the plunger, the internal screw threads in the revolving portion and the threads on the enlarged portion of the plunger being adapted to cooperate and thereby provide a means for the adjustment of the jaws.

3. A wrench comprising a fixed cylindrical sleeve, semi-cylindrical halves within said sleeve, extensions formed at the upper extremities of the semi-cylindrical halves,

jaws pivotally secured intermediate the extensions, a plunger slidable through the semi-cylindrical halves, an enlarged screw threaded portion formed at the inner extremity of the plunger, a rotatable member, said rotatable member being internally screw threaded and adapted to cooperate with the enlarged portion on the plunger, a revoluble sleeve secured to the rotatable member, and means at the end of the plunger opposite the enlarged portion to adjust the jaws when the sleeve is revolved.

In testimony whereof I affix my signature in presence of two witnesses. 1
